3.3 Generative Ground
3.3.1 Generative Section
Construct a generative longitudinal and - cross section, as well as a generative horizontal section (plan) from your paper Testing Ground. Use Rhino curves (2D) to generate the geometry; export to Illustrator and adjust line weights and - types.
A Generative Section is based on the precise information registered on a cutting plane through the paper model; points are measured, the actual model may be cut or remain intact. The measured section is the first layer of several that constitute the Generative Section. Polygonal Rhino lines (degree 2 curves) are most fit to incorporate the many points of the recorded data.
The second layer is based on Nurbs (degree 3 curves) and economizes control points to transpose the first "as is" section into a curve section of equivalent qualities. Every successive layer manipulates the control points, exaggerating the curve behavior and enhancing the Testing Ground's sectional qualities. A speculative drawing emerges, the Generative Section.
3.3.2 Generative Envelope
As a parallel investigation to the GC exercise 3.2.3, the bent, continuous surface is re-generated as a Nurb Surface, this time in Rhino. Revisit your Mesh Matrix and once more identify the generating Site Curves of the selected meshes.
Take the Nurb Curves out of the flat plane by carefully pulling their control points in the third dimension. Loft the curves, and employ additional Rhino surface tools. These moves are informed by the manipulations of the paper Testing Ground (cut, bend).
Follow the steps of "1.5 Site Mesh" and apply the mesh and triangulation tools previously calibrated in the Mesh Matrix. An advanced triangulated surface of extreme and continuous scalar change emerges, the Generative 3D envelope.
Cut sections through your digital model (use Rhino function of topolines), export to Illustrator and compare the sectional arrays to the Generative Sections developed in 3.3.1.
3.3.3 Generative Ground GC
Import the Generative Envelope 3.3.2 into GC. Use the prepared procedure and script package (studio blog: 20070216) to import the 3D Rhino Mesh into GC as shapes. Populate the Generative Ground GC with an improved component (mc_studentfirstname_x). Build a sample region in paper, and test its performance.
Cut a longitudinal and cross section, as well as a horizontal section (plan) through the tectonic GC model.
Size the sections to an appropriate architectural scale (1/2" or 1/4") and give some consideration to the human scale. Compare the drawing to a (partial) section through one floor of your precedent library; it shall include floor, ceiling, exterior wall/ façade and furniture. Identify the programmatic potential of your Generative Ground. Feed your findings into the next generation of the Generative Envelope.
